The AirTAC GFR300C10JC2W AirTAC Filter Regulator, PT3/8, 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR300C10JC2W is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 5 um element (the finer of the two catalogue grades) and lets you set downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment range. Ports are PT3/8 (3/8 in, PT thread standard), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing. The polycarbonate bowl carries a differential-pressure drain, and this configuration is fitted with an external round gauge scaled in psi. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part in the size 300 class of the GFR range, which spans sizes 200 to 600 with port options from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, gauge styles and pressure scales, and G or NPT thread variants to order. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding the air cylinder of a small stamping or punch press: the 5 um element keeps wear particles and water out of the valve and cylinder, while the regulator holds the set pressure that determines forming force.
Mounted at a workshop drop feeding air tools and spray guns, where the finer 5 um grade protects paint work from water spotting and the psi-scaled gauge lets technicians set tool pressure directly.
Conditioning the supply to diverters, clamps and pushers on a bottling or cartoning conveyor, so actuator speed and grip force stay repeatable as the compressor header pressure wanders.
Size 300 with PT3/8 ports sits in the middle of the GFR range; step up to size 400/600 or down to size 200 according to the flow your line needs. The 5 um element (code W) suits points of use that see finer contamination than the standard 40 um grade, at the cost of a denser element to keep clean. The differential-pressure drain handles condensate without a manual routine; choose a manual-drain variant if you prefer a deliberate, supervised dump. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket can be added if this one ships without it.
Because AirTAC publishes flow for this series as curves and not as a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet curves before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as performance curves rather than a single rated number, so we do not state a l/min or SCFM figure. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing against the datasheet curves on request before you order.
The W in the model code selects the optional 5 um filtration grade; the catalogue default for the GFR series is 40 um. The 5 um element suits downstream equipment that is sensitive to finer water and particulate carryover, while 40 um remains the right choice for general plant air ahead of coarser consumers.
